DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 131,310, dated July 1,1890.

Application filed 'Eebruarylfi, 1890. Serial No. 340,552. (No model.)

To all whom it may concern! Be it known that I, SAMUEL D. ASHMORE, acitizen of the United States, residing at Girard, in the county ofCrawford and State of Kansas, have invented a new and useful Door- Stop,of which the following is a specification.

This invention has relation to door-stops, whereby the door may bemaintained at any point of its opening.

The objects and advantages of the invention, together with the novelfeatures thereof, will hereinafter appear, and be particularly pointedout in the claims.

Referring to the drawings, Figure 1 is a perspective of a door-casing,its door, and a stop constructed in accordance with my invention. Fig. 2is an enlarged perspective of the stop detached. Fig. 3 is a detail intransverse vertical section of the adjusting-box.

Like numerals of reference indicate like parts in all the figures of thedrawings.

- The door-jamb 1 and door 2 are of the usual construction, and thelatter is hinged to the former, as at 3, in the ordinary manner. Theupper bar of the jamb 1 has secured thereto the triangular bracket 4,the rear end of which is provided with a securing-plate 5, through whichis inserted screws 6, passing into the j amb and serving to hold thebracket securely in position.

8 represents a hollow metal box provided at its rear sides with lateralsecuring-lugs 9, through which are passed screws 10, taking into thefront face of the door near its upper edge. Verticallyopposite bearings11 are formed in the upper and lower walls of the box, and mounted formovement in the same is a rod 12, the upper portion of which iscylindrical, as at 13, and is mounted for movement in a slot 14, formedlongitudinally in an arm 15, the rearend of the arm being pivoted to thebracket 4, as at 16. Above the arm the rod is provided with a disk orclampinghead 17, and below its cylindrical portion is provided with acentral squared portion 18, which corresponds in shape to theupper-bearing opening, and hence is prevented from turning or rotatingwithin the opening, and yet permitted to have longitudinal movementtherein. The lower end of the rod depends considerably below the boX andis cylindrical, as at 20, and inclosing the same is a bindingsleeve 21,below which there is threaded on the end of the rod a thumb-nut 22. Aspring 23 encircles the rod and has its upper terminal connectedthereto, the lower terminal resting upon the bottom of the box, saidspring serving to normally force the rod upward, so that theclamping-disk at the upperend of the same will not exert pressure uponthe slotted arm, and thereby offer resistance to a perfectly-easyoperation of the door when not desired.

It is apparent that by rotating the screw upon the rod to the right thebinding-sleeve, coming against the under portion of the bottom of thebox, will serve to draw the rod downward and bind its clamping-disk uponthe slotted arm. By this means the door may be stopped or checked at anypoint and against any accidental closing.

When it is desired that the door shall operate in the usual manner, theset-nut or burr is simply rotated to the left, and the coiled springmounted within the box serves to elevate the rod slightly, and thusremove the binding or clamping head or disk from contact with theslotted arm.

Having thus described my invention, what I claim is- 1. Thecombination,with the bracket 4, connected to the jamb, the hollow box 9,secured to the door, the adjustable rod 12, having an upper plainportion and a lower threaded portion mounted for vertical reciprocationin the box and terminating at one end in a clamping-head and provided atits other end with a binding-nut, and an arm 15, pivoted to the bracketand having a slot for the reception of the rod and adapted to be boundby the clamping-head, substantially as specified.

2. The combination, with the bracket 4, 0011* nected to the jamb, thehollow box 9, secured to the door, the adjustable rod 12, having a plainbody portion adapted for vertical reciprocation in thebox andterminating at one end in a clamping-head, provided at its other endwith a binding-nut, and provided between its ends with a squared bodyportion fitting a similar opening in the box, a coiled spring mountedwithin the box around the rod and my own I have hereto affixed mysignature in acting to normally elevate the same, and an presence of twoWitnesses. arm 15, pivoted to the bracket and having a slot for thereception of the rod and adapted SAMUEL D. ASI-IMORE. 5 to be bound bythe clamping-head, substan- WVitnesses:

tiaiiy as specified. O. H. PHILLIPS,

In testimony that I claim the foregoing as C. M. CURTIS.
